Laser Engraving

Laser engraving is a process that removes a microscopic layer in a material with short bursts of energy in a defined area. This creates a permanent mark or engraving on the material. The laser beam is extremely precise and can create marks as small as 0.15mm.

The JPT 60W MOPA fibre laser is a high-performance laser marking machine manufactured by JPT Laser in China. It is a versatile machine that can mark a variety of materials including metal, plastic, and wood.

The JPT 60W MOPA uses a main oscillator power amplifier (MOPA) configuration that enables high performance and fast marking. The MOPA configuration also allows precise control of the laser pulse width and frequency, which is important for achieving high quality marking results. In practice, this means that the smallest letter size can be as small as 0.15mm.

The JPT 60W MOPA has a working area of 175 x 175mm, which can be increased to 300 x 300mm with the aid of a movable table. The maximum marking speed is 7000mm/s.

Screen Printing and Uv Printing

SCREEN AND UV PRINTING

We offer UV printing and screen-printing services. UV printing is a fast and efficient printing process that produces high quality prints on a variety of materials, while screen printing is a more affordable solution that is more suitable for larger quantities.

UV PRINTING

With Mimaki’s UV printers, you can print the text or image of your choice on a product made of any material. UV printing is applicable to a wide range of materials such as metal, plastic, glass, or paper.

The printer is intended for the business of printing corporate gifts, trophies, and plaques, in the cosmetics and electronics industry, in the printing of ID cards and security labels, etc. The printer uses CMYK inks with one additional white colour and one additional special colour – currently, this can be a protective varnish.

Screen printing is a type of printing used to transfer ink or colour to a surface through a screen. Screen printing can be used to print on a variety of materials such as fabric, paper, plastic and metal.

The advantages of screen printing are high print quality, strong print adhesion and low cost for printing large batches.

Powder Coating

admin — Tue, 29 Aug 2023 16:29:32 +0000

Powder Coating

In powder coating, powder paint is applied to the surface of the selected object using a special gun that works on the principle of electrostatics. This method of powder coating can be used to treat various types of metal products, which can be coated in any colour you wish, and then baked in an oven.

Powder coating has a number of advantages over other techniques, as it is more environmentally friendly and, in addition to better paint yield, it achieves more specific colour effects.

Environmentally friendly: Powder coating is a more environmentally friendly method as it does not contain solvents and does not produce harmful emissions.
Better paint utilization: When powder coating is used, the paint is better utilized as most of the powder adheres to the surface and less of it remains unused.
Specific colour effects: Powder coating allows more specific and unique colour effects to be achieved on surfaces.

Preparation for powder coating involves, among other activities, washing the pieces by adding Surtec 601 all-purpose detergent. The process of adding this detergent is called phosphating. The phosphate degreases the pieces and lightly chemicaly wears the material. This process results in a strong adhesion of the paint on all types of metal.

The paint shop boasts a demi system, or water demineralization process, which removes limescale and all impurities. This process ensures that the pieces are washed with consistently clean water, without any traces of detergent or degreaser, while at the same time achieving better paint adhesion. The demineralization process also allows us to be more economical and ecological, as the washing water is changed once every three months.

Welding and Grinding

Welding and Grinding

Welding is carried out by professionally qualified and experienced welders, and the Trumpf TruLaser Weld 5000 laser welding machine allows us to assemble all the elements into a finished product, which is then treated by grinding. Grinding removes excess residues and imperfections from the product and ensures a professional and sophisticated final appearance.

LASER WELDING

Using our Trumpf robotic laser welding machine, we can achieve the highest quality welds. Depending on the requirements, completely new weld geometries are possible, achieved without or with the use of material addition. High welding speed and high quality and appearance of the weld are achieved, so in most cases no grinding or polishing is required.

MIG/MAG AND TIG WELDING

MIG, MAG in TIG welding are welding processes that use an electric current to weld and join two or more pieces of metal.

For MIG in MAG welding, a wire is fed into the welding zone, while TIG welding uses a tungsten electrode.

CAPACITOR DISCHARGE WELDING

Capacitor discharge stud welding is carried out with two larger Soyer stand-alone CNC welding machines, which offer spot welding with a movable arm and a programmed selection of different bolt sizes. The welding machine allows very precise, fast, and reproducible stud welding.

RESISTANCE WELDING

Spot welding of two steel weldments using the electric current. In spot welding, two oppositely positioned copper electrodes are pressed together and the electric current is directed to a small point, welding the piece in 10–100 milliseconds. The thickness of the material suitable for welding ranges from 0.5 to 3 mm.

GRINDING AND DEBURRING

By grinding the product, we remove excess residues and imperfections and ensure the design and a professional and sophisticated final appearance of the product. We offer both machine rust removal and manual grinding of the product.

Insert Metal Stamping

Laser Cutting and Punching

admin — Tue, 29 Aug 2023 16:26:04 +0000

Laser Cutting and Punching

To perform a combination of CNC punching and laser cutting, we use state-of-the-art machines made by Amada and Trumpf GmbH which are among the best in the industry.

With the help of a feeding and unloading system, Amada enables the serial production of products without the assistance of an employee. We can produce even the most demanding products, which are, due to the superior, almost fully robotic technology, precise and of high quality, and its production is extremely fast. In addition to conventional laser cutting, we also offer cutting with Amada fibre technology (industrial fibre laser cutting machine by Amada), which does not use CO2. The cutting point is 100 times smaller, which is ideal for cutting reflective metal materials. It is 3 times more efficient, with a third of the electricity consumed compared to CO2 lasers.
